from the end portion 15 of the bolt 12.

The 1001: Will then, of course, be opened and the pins 19 will bedisposed in the outer portions of the slots 24 of the tumblers asclearly shown in Fig. 3. This being the case on relative turningmovement of the plates 10' and 11 with the bar 19 as an axis thetumblers will retain their positions relatively and relative to the bar16 and pins 19. It will, of course, be understood that the free endportion of the bar 16 is capable of sliding and rotary movement in theopening 13 of plate 10.

Secured to the plate 10 as for example by rivets or pins 26 is a member27 which extends in the direction of plate 11 across the top of thetumblers and has a downwardly extending flange 28 provided with anopening 29 through which the bar 16 snugly fits.

Since the member 27 is rigid with the plate 10 it is obvious that thismember does not move with the plate 11 and bar 16 as the lock is openedand closed. The location of the flange 28 of member 27 is such that thedistance between the inner surface of the flange and the plate 10 issuiiicient only to accommodate the tumblers 20.

This member'serves to prevent movement of the tumblers along the bar 16and when the lock is to be opened the member prevents movement of thetumblers in a direction away from the plate 10. Further, when the lockis opened the pin 19 closest to the plate 11 will engage the flange 28of member 27 and limit the outward movement of the bar 16 in a manner toprevent the bar being entirely removed from the recess or opening 13 inthe plate 10 and from the tumblers 20. This last action it will beunderstood pre vents the look from being accidentally disassembled.

Means may be provided to prevent casual turning of the tumblers 20whereby in the opening of the lock each tumbler after adjustmentwillremain in its adjusted position while the other tumblers are beingadjusted to position permitting the lock to open. This means as heredisclosed comprises a series of fingers or dogs 30 which may be struckfrom the member 27 and which are carried by this member as clearly shownin Figs. 1, 2 and 3. These fingers 3O engage the enlargedtoothedportions 25 of the tumblers and enter between the grooves orteeth therein in such a manner as to prevent casual movement of thetumblers. However there is but a spring or frictional engagement betweenthe fingers 1 and the portions 25 of the tumblers and the tumblers maybe rotated against the action of fingers.

Means may also be provided for shifting the plate 11 outwardly or toopen position on the tumblers being adjusted to align their slots 2 1with the respective pins 19. This means as here disclosed comprises acoil spring 31 arranged on thebar 16 in sueha' manner as to engage theflange 28 of the member 27 and to have a portion extending into therecess 18 in the plate 11 whereby to engage the closed end of. thisrecess. It is open'position as shown in Fig. 3 the plates 10- and 11 maybe rotated relatively whereby to leave the end portion 15 of the bolt 12entirely unencumbered. That is, the plate 11 may be rotated forwardlyfrom the position shown in Fig. 3 while the plate 10 and bolt 12may berotated rearwardly from the position shown in that figure. Thisparticular action is possible since movement of the plate 11 will resultin rotary movement of the tumblers forwardly below the fingers or dogs30 while movement of thefplate 10 will result in a movement of the saidfingers relative to the tumblers. I

In addition to serving to shift the lock f from the position shown inFig. 1 to that shown in Fig. 2 immediately on the tumblers beingadjusted to align their slots 24 with the pins 19 the spring 31 servesto prevent casual closing of the lock. Itwill be understood that thelock must not be closed or that the bar 16 must not be moved through thetumbler toward locking position except when the plates 10 and 11 are insuch relative position that the bolt 12 enters the recess 1 1.Otherwise, the combination might be lost with the parts locked in auseless position.

As disclosed the combination of the lock is 2581 ano it will be notedthat the plate 10 carries a mark 32 with which the proper numbers arealigned in order to bring the slots 24: of the various tumblers intoalignment with the respective pins 19 with which the tumblers areassociated.

In assembling the-lock thus far described the bar 16 may have its enddisposed in the recess 13 of the plate 10 after which the tumblers areslipped onto the bar. Next, the member 27 is assembled'with its flange28 about the bar and this member may then be secured to the plate 10 asby the rivets or pins 26. The spring 31 now disposed over the bar andthe plate 11 applied and secured as by heading the end of the bar at 17.

Fig. 6 shows a slight modified construction wherein a member 33corresponding with the member 27 of the embodiment first described isinte ral with the plate 10. This member 33 also has a flange 34 providedwith an opening 35*to receive the bar 16. Through its flange 34c andentering into its opening 35 the member 33 is provided with a notch 36of the dimensions required to permit of the passing of the pins 19therethrough- V In assembling the lock on a frame such as is shown inFig. 6 the bar 16 has its passed through the opening 35 in the flange3st, the notch 36 'permitting'the pins 19 to pass. As the bar is fedthrough or threaded through the opening 35 the tumblers are applied andthe inserted end of the bar finally enters the opening13in the plate 10.Of course, with the use of a frame as shown in Fig. 6, the bar 16 may beintegral with the plate 11 and in that event the spring 31 would beapplied before the bar was started through the opening 35 of the flange34 of the member 33.

It is apparent that the notch 36 is shown as 180 degrees from thelocation of the pins 90 when the lock is closed. Therefore, when thelock is opened by the spring 31 as shown in Fig. 3 the bar 16 will notpass out through the opening 35 butwill have its movement limited byengagement of the innermost pin 19 with the flange 84: as described inconnection with the form of invention previously considered. However,this look may be easily disassembled when opened and the tumblersrearranged to give a different combination.
